Reaction Conditions

Reaction Steps

A mixture of 2-(benzyloxy)-1-chloro-3-fluorobenzene (3 g, 12.71 mmol), dioxane (6 ml), KOH (0.78 g, 14 mmol), water (6 ml), Tris(dibenzylideneacetone)dipalladium (0.12 g, 0.13 mmol) and 2-di-tertbutylphosphine-2,4,6-triisopropylbiphenyl (0.22 g, 0.51 mmol) was flushed with N2 and heated under microwave radiation at 120° C. for 7 min. HCl (1 N) was added and the solution was extracted with EtOAc. The combined organic phases were dried (Na2SO4) and evaporated to dryness. Flash column chromatography (isooctane/EtOAc) yielded the title compound (1.86 g). MS m/z (rel. intensity, 70 eV) 218 (M+, 4), 92 (8), 91 (bp), 65 (13), 51 (9).
